Figure 5From: Meiotic errors followed by two parallel postzygotic trisomy rescue events are a frequent cause of constitutional segmental mosaicismShort tandem repeat analysis on DNA of cases 2, 4 and 5 and parental DNA. A) Case 2 has a difference in peak ratios in marker D15S130 corresponding to two identical paternal alleles and one maternal allele. B) Case 4 demonstrates a 2:1 peak ratio in marker D1S2635 corresponding to two identical paternal alleles and one maternal allele. C) Case 5 shows a duplication of the maternal allele in marker D2S1780. C: case, F: father, M: mother.Back to article page
